Studying the Human Body – Proportions & Symmetry

Our study of Konos this year begins with the unit Cooperation, and the topic “Systems of the Human Body”. While this volume of Konos contains some great ideas of activities to enhance the study of the human body, I have found this book, How the Body Works, by Steve Parker, to be an indispensable resource, both as a source of information, and as a source of some really fun experiments!

Some examples:

Body Proportions

We made a “human graph” to show how the body proportions varied by person.

One thing I found interesting was that, while “Ant” (2nd in line) is a bit taller than his older brother “Gator”, they are almost exactly the same, proportionally.

Another thing I had never noticed is that, while “Dinky Tumblina” is only 22 months younger than “Ant”, her shoulder only comes about to his elbow!

For your reference, using my web-safe names, pictured from left to right are: Gator (13), Ant (12), Dinky Tumblina (10), Lefty (9), Boo (7), Cricket (6), and Curly-Top (4). (My oldest and youngest are not pictured).

Doesn’t Ant look thrilled? He is NOT a morning person!

Facial Symmetry

How symmetrical is your face?

For this experiment, I took photos of each of the children’s faces from the front (looking straight ahead). I then used my photo editing program to make a mirror image of each one. I sent these photos to Walgreen’s photo center online, to be picked up (2 copies of each) at our local Walgreen’s.

Once we had our photos, we used a paper cutter to cut each photo in half. In matching the photos up, with mirror image halves matched with the halves of the originals, we were able to see just how symmetrical our faces really were (or weren’t)! The differences were amazing. And more amazing still was how some of the children’s faces were WAY off when it came to symmetry, while two of the children were found to have almost perfectly symmetrical faces!




Gator’s was especially amusing. The bottom left photo is the original, and the bottom right is the mirrored image, while the top two are the symmetry photos. In one of the symmetry photos his face looks fat, while in the others his face is thin and he has fangs!

    Thank you for the inspiring post! I am starting my year this year using KONOS; we are starting with the Attentiveness unit to study the five senses. I think the book you mentioned could/would be helpful for this unit as well. I think my library will have it; I am definitely going to go check. Blessings! ~Flybaby

    I know my kiddos would love KONOS, but I’m too intimidated by the amount of planning work for me. This looks great! Maybe I’ll get the book anyway, just in case LOL…
